Ok, so I have guppies (not goldfish), and one of my friends owns goldfish. I wanted to know if I could give her some baby brine shrimp because her goldfish only eat flakes and flakes and flakes and- (you get the point). I also feel super bad for them because she keeps four comet/common goldfish in a filtered 10 gallon, even though I keep telling her she needs to get an 80 gallon or something that is at least the bare minimum. But she always argues with me that her fish are "really happy". Anyways, can goldifish eat baby brine shrimp? I read somewhere that they can't digest it, but I don't know.

4 months is nothing, they'll start kicking the bucket one at a time once they're stunted/poisoned enough really A 40 gallon would be the absolute minimum for these fish, would she listen to that at least? (Since it's a tad smaller than an 80?)It's so very cruel to just assume they're thriving in there just because they're surviving.
